never mind, just don’t forgive him. easy.
you can remember every small things from past, so in this life don’t repeat again the same pattern of your life in this life. again, are you sure that is your past and not illusion? as I know, you can’t remember everything. only the certain things in you life that what the soul took birth in this life to complete those unsuccessful events, the desire, etc etc etc. and the soul only can remember the things of past when its (soul) is attached with body. your memories restored in you brain. soul alone without body can’t restored any memories. for memories all human had 7 types of memories. its complex and here is not medical class. I just share very few of my knowledge. hope you can find what the impact of past life, the actions of past, karma of that. take its easy. chill
